•
With a normal RC, key in sequence "MUTE" followed by
"062599" and "OK".
•
When you transmit the commands "DIAGNOSE" - "99" -
"OK" with ComPair (or with a DST).
•
If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4
Error Codes
In case of non-intermittent faults, clear the error buffer before
you begin the repair. This to ensure that old error codes are no
longer present. Before clearing the buffer, write down the
content, as this history can give you significant information.

Note: If error 3 or error 55 appears, sometimes error 16 is also logged. Error 16 is a non existing error.
Note:
•
Error codes 1, 6, or 18 are protection codes and in this
case, supplies of some circuits will be switched "off". Also,
in protection, the LED will blink the number of times
equivalent to the most recent error code.
5.6
The Blinking LED Procedure
5.6.1
Introduction
Via this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful for fault
finding, when there is no picture.
When the SDM is activated, the front LED will show (blink) the
contents of the error-buffer. Error-codes > 10 are shown as
follows:
–
A long blink of 750 ms (which is an indication of the decimal
digit),
–
A pause of 1.5 s,
–
"n" short blinks (where "n" = 1 - 9),
–
When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,
–
The sequence starts again.

If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).
There are various errors:
2
•
I
C device errors.
2
•
I
C bus errors.
•
Protection errors.
•
Errors not related to an I
–
FEM (Falconic with Embedded Memory) (Error 26):
at start-up, after initialisation of the PICNIC, the
presence of the FEM can be checked.
–
Eagle (Error 27): at start-up, after initialisation of the
PICNIC, the presence of the Eagle can be checked.

Note: For error codes >100, the first two digits (hundred-and-
ten) are considered as one digit (one long blink)
Example: Error 12 9 6 121 0.
After activation of the SDM, the front LED will show:
–
1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1.5 s,
–
2 short blinks followed by a pause of 3 s,
–
9 short blinks followed by a pause of 3 s,
–
6 short blinks followed by a pause of 3 s,
–
12 long blinks of 750 ms (which is an indication of "120")
followed by a pause of 1.5 s,
–
1 short blink followed by a pause of 3 s,
–
1 long blink of 3 s to finish the sequence,
–
The sequence starts again.
Note: If errors 1, 6, or 18 occur, the LED always gives the last
occurred error even if the TV is NOT in service mode.
5.6.2
How To Activate
Use one of the following methods:
•
Activate the SDM (only via soldering pads marked "SDM"
on SSB, see figure "Service pads"). The blinking front LED
will show the entire contents of the error buffer (this works
in "normal operation" mode and in "protection" mode).
